NEEDLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 758,473, dated April 26, 1904.

Application filed August 10, 1903.

To all whom it may concern:

Be it known that I, ERNEsT CHARLES REED, paper manufacturer, a subject of the King of Great Britain and Ireland, residing at Raamsdonk, North Brabant, in the Kingdom of the Netherlands, have invented certain new and useful Improvements in Needle-Lubricators, of which the following is a specification.

My invention relates to needle-lubricatorsthat is to say, lubricators in which a bottle or container for the lubricant is used together with a needle or rod passing through an outlet-passage from the bottle or container, the said passage being of a size to allow a proper quantity of lubricant to pass through it and around the needle or rod when the outer end of the needle or rod is in contact witha shaft or other moving part to be lubricated. In such lubricators grit and dirt present in the lubricant pass therewith into the passage from the bottle, and such grit and dirt as may remain in the said passage impede the proper action of the needle or rod, while grit and dirt which pass out therefrom cause heating of the bearings or surfaces to the lubrication of which the lubricator is applied.

The object of my invention is to overcome these objections and to provide a needle-lubricator in which grit and dirt that may be in the lubricant in the bottle or container are prevented from finding their way to the passage through the stopper.

According to my invention I support within the bottle or container a mantle or tube of textile fabric. and arranged in such a way as to allow the lubricant to pass through the said mantle or tube, but to intercept grit and dirt, while leaving a space inside the mantle or tube of filtering material and its support to allow the needle or rod to move freely within the bottle or container.

I will describe, with reference to the accompanying drawings, a lubricator in accordance with my invention, premising that I do not limit myself to the precise details shown therein, as they can be considerably varied without departing from the nature of my invention.

Figure 1 is an elevation, and Fig. 2 is a vertical section, of a lubricator constructed in ac- Serial No. 169,028. (No model.)

D is a perforated tubular support closed at its upper end, its other end beingfitted into a circular recess t made in the stopper B-concentrically with the tube 6. Over the whole of the perforated part of the support D is passed a mantle or tube E of filtering material, which will allow of the passage of the lubricant, butintercept grit and dirt, a very suitable and convenient form of material being knitted cotton resembling a circular lampwick. The support D and mantle or tube E completely separate the space in which the needle or rod 0 moves from the space into which the lubricant is introduced into the bottle or-container, and no lubricant that has not passed through the mantle or tube of filtering material E can gain access to the space within the said mantle or tube of filtering material and its support and to the outlet-tube b, and consequently no grit or dirt can get into the said tube 6 or pass to the surfaces being lubricated, and therefore the needle C always works freely and there is no danger of grit or dirt which may be in the main space in the bottle or container passing to the bearings or the like and causing overheating thereof. The mantle or tube of filtering material E preferably has its edges gummed to make them smooth, and the said mantle or tube E (and also its support D when required) can be easily removed and cleansed or a clean mantle or tube put in place.

It will be evident that the details described can be considerably varied without departing from the nature of my invention. For example, the support D may be made of wiregauze or of slitted material or the like or of bars or of a coiled wire, and the inner end may be open and covered by an end formed on the mantle or tube of filtering material or be closed by a cork or otherwise. If desired, the lower end'of the support D can be screwed into the circular recess 7).

I am aware that lubricators have been provided with filtering material; but this has been done by placing loose material, such as hemp-waste, in the passage from the bottle or container, and such material so applied has not been eflicient in excluding dirt, nor has it been arranged so as to allow a space for the needle or rod to move in, and therefore no needle or rod has been used in such lubricators, and they have been without the control which it is the function of the needle or rod to exercise during the working of the machinery, and the passage for lubricant has been always open, and lubricant has Wastefully escaped when the machinery is at rest;

but in the arrangement according to my invention all the advantages of needle-lubricators are retained, while there is secured the additional advantage of preventing access of grit and dirt to the tube 6 and to the surfaces being lubricated.

I claim as my invention A needle-lubricator,comprising a container, a stopper; a central tubular opening therethrough, a needle passing through said opening into the container, a perforated support surrounding said needle, and a filtering material of textile fabric covering the perforated support and separating the needle from the container, substantially as described.

In testimony whereof l aflix my signature in the presence of two witnesses.
